I am a first time mother, my daughter is now 5 months old. Something I have learned is that all babies develop at WAY different rates! Kaylee was rolling over with no problem at 3 months, and my friends daughter (1 1/2 months older - so 4 1/2 months) had barely attempted to roll over at all.
A book that helped me though, to look for a guideline and knowing what to expect was
"Your Baby's First Year" - Steven P. Shelov, M.D.
It cover everything from birthing your baby all the way up through your child's first birthday.
Congratulation's on your new arrival momma, and you can e-mail me if you have any questions I might be able to help with :)
